Choosing the Right Hardwood Decking for Long-Term Performance

(Photo above is of our wood decking project at Marina Bay Sands, Singapore in 2010.)

A good deck lives outdoors full time. Sun, rain, humidity, snow, and foot traffic test it every day. Hardwood performs well because its density and natural oils slow rot, resist insects, and maintain structural stability.

Below are the hardwood decking species we supply and why each one performs well in real-world use.

Teak

Teak contains high levels of natural oils and silica. These reduce water absorption and discourage termites. This is why boat builders, not just homeowners, use teak, and why many consider it the benchmark for decay resistance.

Teak suits clients who want long-term stability with minimal movement. When left untreated, it weathers to a silver-grey patina that many architects favour for a calm, timeless appearance.

Merbau

Merbau offers strength and strong visual character. It handles heavy loads and high foot traffic well, making it suitable for terraces and commercial decks. Freshly milled, it shows a rich orange-brown tone that matures into a deep reddish-brown and remains rich with regular oiling. Its high resistance to rot and insects makes it a reliable choice where durability matters.

Yellow Balau

Yellow Balau delivers excellent hardness at a practical price point. Builders often select it for large outdoor decks where structural strength matters. It performs well under moisture and wear, which explains its frequent use in bridges and boardwalks. Expect a lighter brown tone that darkens slightly with age.

Red Balau

Red Balau sits visually closer to Merbau while remaining distinct. It provides strong load-bearing capacity and good resistance to decay. Clients choose it when they want a darker, more uniform finish without stepping into premium pricing.

Kapur

Kapur balances performance with ease of installation. It machines cleanly and installs efficiently, reducing on-site labour time. Kapur works well for residential decks and covered outdoor areas. Its pale to medium brown tone suits modern designs that favour lighter colour palettes.

Keruing

Keruing prioritises structural strength. Its high density makes it suitable for decks that experience frequent use or require strong sub-structure support. Builders often specify Keruing for commercial projects and large outdoor platforms where durability outweighs colour consistency.

A note on selection

Do not choose decking based on appearance alone. Climate, exposure, foot traffic, and maintenance tolerance matter more. A poolside deck faces very different stresses compared to a covered balcony.

We work with these hardwood species regularly and can recommend alternatives if your project requires a specific performance profile or budget range. A well-chosen deck should age predictably, not create problems later.
